  2. Electrostatic precipitator - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_precipitator

    An electrostatic precipitator ( ESP) is a filterless device that removes fine particles, such as dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. [1]

    en.wikipedia.org/wiki/Frederick_Gardner_Cottrell

    Frederick Gardner Cottrell (January 10, 1877 – November 16, 1948) was an American physical chemist, inventor and philanthropist.He is best known for his invention of the electrostatic precipitator, one of the first inventions designed to eliminate air pollution—and for establishing the Research Corporation for Science Advancement, a foundation that has funded scientific research since 1912.

  4. Rapper (electrostatic precipitation) - Wikipedia

    en.wikipedia.org/wiki/Rapper_(electrostatic...

    Rapper (electrostatic precipitation) Rappers are used to transmit strong shearing forces to collecting plates in order to release deposited dust particles. Rapping is the process by which electrodes and particles are broken apart by vibrations from the rappers. Often used in electrostatic precipitators, rappers relapse the caked on dust layer ...

    en.wikipedia.org/wiki/Corona_discharge

    Corona discharges represent a significant power loss for electric utilities. Corona discharge from a spoon attached to the high voltage terminal of a Tesla coil. A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage.

  6. Electrostatic separator - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_separator

    Electrostatic Separator. An electrostatic separator is a device for separating particles by mass in a low energy charged beam. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution. Electrostatic separation is a process that uses electrostatic charges ...

  7. Dust collector - Wikipedia

    en.wikipedia.org/wiki/Dust_collector

    Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere. Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis.

    en.wikipedia.org/wiki/Electrostatics

    Therefore, the electrostatic field everywhere inside a conductive object is zero, and the electrostatic potential is constant. The electric field, E {\displaystyle \mathbf {E} } , in units of Newtons per Coulomb or volts per meter, is a vector field that can be defined everywhere, except at the location of point charges (where it diverges to ...

  9. Electro precipitation - Wikipedia

    en.wikipedia.org/wiki/Electro_precipitation

    Electro precipitation. Electro precipitation is the removal of heavy metal ions, charged colloids, emulsions and microorganisms by passing direct electric current (introduced via parallel plates constructed of various metals that are selected to optimize the removal process) through contaminated water. [1] [2] Since the targeted contaminants ...
